Title The overall design of new small-caliber rifle system
Abstract
With the development of science and technology, our country's active weapon has exposed many problems to some extent. To shorten the gap between our country's firearms and foreign arms。This paper takes the overall design of the new small caliber rifle as the subject .First, the development of the gun and the development of small caliber weapon are introduced, then By listing of the advantages and disadvantages of China's 56, 95 and 03 rifle, We sum up the lack of firearms designed in our country and then the design idea are presented .By referring to the relevant information, the mechanism and its movement mode of the gun are selected and determined. Finally, the shape of the gun designed by the structure of the gun has been drawn, also, some main parameters of the gun are selected based on ergonomics.
